ENGINE OIL PRESSURE GAUGE : System Description
INFOID:0000000001702234
The engine oil pressure gauge indicates whether the engine oil pressure is low or normal.
The oil pressure gauge is controlled by the IPDM E/R. The IPDM E/R reads the ON/OFF signals from the oil
pressure switch and transmits the oil pressure switch signal to the combination meter via BCM with the CAN
communication line. The oil pressure gauge displays a low or normal indication according to the oil pressure
switch signal received via CAN communication.
